A disk of mass M and radius b is pulled with a constant force F by a thin tape wound around its circumference, sliding on ice without friction. Which of the following is the angular acceleration ( \(\alpha\) ) of the disk?
1
\(\alpha = \frac{2F}{mb}\)
2
\(\alpha = \frac{F}{M} \)
3
\( \alpha = \frac{4 F}{Mb} \)
4
\(\alpha = 0\)
